Exam 16: Nonparametric Methods: Analysis of Ordinal Data

Two movie reviewers gave their ratings (0 to 4 stars) to ten movies released this past month as follows: The rank order correlation is to be used. What is the rank order correlation?

What test is an appropriate substitute for the ANOVA procedure if the assumptions for ANOVA cannot be met?

The following are the ratings (0 to 4) given by 12 individuals for two possible new flavors of soft drinks. Wilcoxon rank-sum is to be used. What is the sum of the ranks for flavor #1?

In the Kruskal-Wallis test for the following data, what is the sum of the ranks for Sample 3?

In the Kruskal-Wallis method, testing for differences among populations is based on the sum of the ________.

To test the hypothesis, the Wilcoxon signed-rank test uses a:

The Wilcoxon signed-rank test can replace the paired t test when the assumptions for t cannot be met.

The ______ test statistic is used to test the significance of the Spearman coefficient of rank correlation.

In testing the significance of Spearman's rank-order coefficient, the alternate hypothesis is ______________________.

Which of the following distribution-free tests would not be an example of a nonparametric method?

The Spearman coefficient of rank correlation requires that observations be _______.

Spearman's rank-order correlation coefficient may assume a value from -1 to +1.

To apply the Kruskal-Wallis test, the samples selected from the populations must be dependent.

In a Kruskal-Wallis test, the null hypothesis states equality among five different populations. The sample size for each population exceeds five. What is the critical value for the test using a 0.05 significance level?

Two movie reviewers gave their ratings (0 to 4 stars) to seven movies released this past month as follows: The Wilcoxon signed-rank test of differences is used. What is the null hypothesis?

A soap manufacturer is experimenting with several formulas of soap powder. Three of the formulas were selected for further testing by a panel of homemakers. The ratings for the three formulas are as follows: What is the sum of the ranks for Formula A?

In a sign test, the test statistic is based on the _______________ distribution.

A nonparametric test requires that the data can be:

What is the test statistic for the sign test if the sample size is large?

What is the difference between chi-square nonparametric tests and nonparametric tests based on ranks?
